BOTTLE-CLOSURE.

Application sled lApril 4, 1919. serial No. 287,432.A

To all when?, it may concern 1 Be it known that I, EMANUEL W. KAISER a citizen of the United States, and a resident of Newark, in the county of Essex and State of New Jersey, have invented new and useful Improvements in Bottle-Closures, of which the following is a specification.

This inventionrelates more particularly to bottle closureswhich are provided with fastening devices of the spring-clip type and adapted to be removed bv the fingers or` withoutv an opener. I

Theobjectsof the invention are to provide an improvedconstruction which will effectively maintain a secure sealing of the bottle; to avoid riveting the parts together and at the same time provide a structure in which the partsy will not readily become separated; to provide a freedom of movement between the parts so as to obtain a firm seating` of the gasket upon the bottle top; to obtain a strong gripping action by the clip without increasing the thickness or resiliency ofthe cap; to secure simplicity of construction and ease of operation, and to obtain other advantages and results as may be i brought out in the following description.

Referring to the accompanying drawings, in which like numerals of reference indicate the same parts throughout the several views.

Figure 1 is a'plan of a closure embodying my invention Fig. 2 is a bottom view of the same;

Fig. '3 is an elevation or edge view of the closure;

Fig. 4 is an elevation at right angles to Fig. 3-

Fig. 5 is a cross-section on line 5-5 of Fig. l;

Fig. 6 is a similar 'cross-sectional view showing the cap mounted upon a bottle top,

` and Fig. 7 is a cross-section on line 7-7 of Fig. 1. l

In the specific embodiment of the invention illustrated in the drawing, the reference numeral 1 indicates a bottle cap having a disk-like crown or body portion. 2 anda peripheral depending flange or skirt 3, said closure adapted to fit over the outside of the mouth end of a bottle 4. As is usual in such devices, a wafer or gasket 5 of cork or other suitable material is carried within the body or crown 2, this gasket 5 sealing'the bottle by being pressed upon the upper end thereof by said crown. The central portion of this I crown 2 is offset upwardly, that is, pressed".

or stamped upto project from the body op-`v positely from the skirt, this offset constitutf' ing a bulge 6.

-F or holding vthe cap upon the'bottle top,`a i lclip 7 is provided the middle part of which extends diametrically across the cap" and direction of the lskirt 3, these downwardly projecting portions of clined toward each other, therebyfc'on'stitut ing jaws 8 for engaging under thebead^9` l around the `upper end ofthe bottle neck". B vv Patented Dec.9, 1919.

downwardly atthe periphery thereof in 'the y the clip 7 being -in 'f' virtue of the resiliency of the clip`,it is held upon the .bottle and the Jaws wedginglv` draw downwardly under the bead 9 therebv seating the gasket 5 firmly upon the bottlefi ltop. It is to be noted that pressure of the 'y l "'75 clip is upon the bulge 6 at the middle ofthe cap, so that the cap will seat properly and uniformly `upon the bottle top irrespective of slight irregularities, the cap having/'a limited freedomof movement with respect to the clip in all directions riveted thereto.

' At the lower ends of the downwardl)- projecting portions or jaws 8 of the clip 7 are provided lin er pieces l0 which preferably project radia ly outward with respect to the cap and which may be engaged by ones lingers for removing the stopper from the bottle. f'

In order to retain the clip and Capassociated inV proper relation at all times, the skirt 3 of the clip is preferably cut away or recessed upwardly from the free edge lof the skirt for such width as necessary to permit the passage of the inwardly sloping jaws 8, 8 therethrough, as at 11, 11, the side edges of and not being such recesses being preferably bent out wardly to provide tabs or ears 12 whichre.- tain the clip upon the cap and limit edgewise displacement and` relative rotation. These the cut-outs or recesses 11, thereby ,prevent- 'ing separation of the parts in any direction,

stopper to a` bottle. Obviously the cap may be forced down upon the lbottle neck, the

Jaws 8 being spread in so doing and snapping .under the bead 9 on the bottle, thereby al drawing the clip down upon the neck. Lat- 221%. when construed in the light of the prior art.

eral displacement.- is prevented because of the dependi'iig'FSkirt 3 of the lcap ttingaround the bottle" top; 'XI-Removal of the stopper is effected by upward pressure upon the'out-v wardly projecting finger pieces 10 provided for that purpose, and it will be noted that these `ingerii'pieces afford suiiicient hold and leverage upon the clip so as not to require any'xtoolsfor the removal thereof from the bottle. f v

Various detail modifications and changes may be made in manufacturing my improved bottle vclosure without ldeparting from the spirit and scope of the invention, and I do not wish to be understood las limitingmyself except as required by the following claims Having thus described the invention, what I claim is:

1. A bottle closure comprising in fcombination a cap, and a resilient clip therefor having a middle cap-engaging portion and bottle engaging and gripping ]aws for se' curing said cap and clip upon a bottle, the jaws also coperating with the cap to permanently' associate the cap and clip Aand at the same time permitting limited rocking movewith respect to the cap.

ment of said associated parts with respect to each other so as to'adjust the cap to a bottle.

2. A Vbottle-.closure comprising in combination a caphaving a skirt and central.YY

cap to a bottle said clip having means for permanently and loosely associating it with the cap, said clip" engaging the cap at its bulge 1n ressing the cap upon a bottle, whereby t'iie cap may adjust itself to a bottle top. Y.

3. In al bottle closure, a cap having a depending skirtvjprovided with outstanding ears, and a clip having al portion extending across the cap and downwardly at opposite sides of the skirt between said ears thereby preventing lateral displacement of the clip 4. In a bottle closure, a cap' having a depending skirt provided at its lower edge with opposite recesses, and a clip having a portion extending across the cap with downwardly and inwardly inclined opposite ends lying insaid recesses.

5. In a bottle closure, a cap having a depending skirt provided at its lower edge with opposite recesses having outstanding ears at their side walls, and a clip having a portion extending across the ycap and downwa-rdly through said recesses between said ears. EMANUEL W. KAISER.
